Fastening arrangement

Abstract

A fastening arrangement comprises a first component that is repeatably releasably fastenable to a second component, and an additional part. The additional part is pivotable about a pivot joint between an open functional position, in which a joining portion of the first component is joinable to a receiving portion of the second component, and a closed functional position, in which the joining portion of the first component is received in the receiving portion of the second component. During a transition between the functional positions, the additional part passes through an unstable dead-center position.
